I have the international G2, and I already got updated with Knock Code over 3 months ago. Personal revelation- I rarely use it. Nonetheless, it’s a cool feature to have, and some users might find it cool to have.
So, Knock-Code create a code made up of 2-8 taps
(personal warning- don’t use 2 taps), and it help make an original way to
unlock and protect your phone. I mean, non-techy people will not know how to
even start. The screen is divided into 4 quarters, and each tap is in one of
the quarters.
